UNITED STATES WILLIAM A. MOORE, OF LAKOTA, IOWA.

RIDGE-ROLL VENTILATOR.

' Application filed February 27, 1928. Serial No. 257,413;

This invention relates to a ventilator for barns, stables and the like,the general object of the invention being to provide a cylindrical-likecasing for enclosing the entire ridge part of a roof and having wings atits sides which are formed with openings and the roof having an openingat its ridge which is in communication with the casing so that air canpass from the building through said opening into the casing and thenpass from the casing through the wings and can enter the buildingthrough the wings and casing and through the opening in the ridge. Thusthe invention will give ventilation all along the roof and at the sametime will prevent the entrance of rain and snow.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts,

to be hereinafter fully described, illustrated in the accompanyingdrawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation of port-ion of a roof, showing the invention in use.

Figure 2 is a transverse sectional view through Figure 1.

Figure 3 is a view similar to Figure 2, but showing the inventionapplied to a shingle roof.

In these views, 1 indicates the cylindrical portion of the ventilatorand 2 indicates the wings thereof which extend downwardly and outwardlyfrom the cylindrical portion and these wings are adapted to be fastenedto the roof, one on each side of the ridge thereof by any suitablemeans. The drawing shows a stepped strip 3 for fastening each wing tothe roof. This strip has its lower parts fastened to the roof and itsupper portions to the wings so that the wings are held in spacedrelation to the roof, thus permitting air to enter or escape from thecylindrical part 1 between the roof and the Wings. An opening 4 isformed in the ridge of the roof and the metal with which the roof iscovered has its edges, at the opening, turned upwardly as at 5, toprovide a tapered opening 6 for connecting the interior of the buildingwith the ventilator. The edges of the metal portions 5 extend above thejunction of the wings with the casing so that there is no danger of rainor snow entering the building through the opening.

In Figure 3, the invention is shown as applied to a shingle roof and inthis case, the metal flashings 7 are extended to form the restrictedopening 6 for connecting the building with the ventilator.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to he understood that I may make changes in the constructionand in the combination and arrangement of the several parts, )rovidedthat such changes fall within the scope of the appended claim.

l/Vhat I claim is In combination with abuilding having an opening in itsridge, a ventilator comprising a casing of cylindrical shape in crosssection with the lower part open, a downwardly and outwardly extendingwing connected with each edge wall of the opening, spacer stripsconnected with the lower faces of the wings and with the roof, one oneach side of the opening therein for holding the ventilator in spacedrelation with the roof with the cylindrical part directly over theopening in the roof and metal strips attached to the roof, one on eachside of the opening therein, with their upper parts curving upwardly andoutwardly into the ventilator, with their upper edges entering thecylindrical part of the ventilator, whereby the cylindrical part is indirefct communication with the opening in the roo In testimony whereof Iafiix my signature.
